mongodb 安裝配置實踐

標籤：mongodb安裝文檔

1. 首先從官網下載mongodb的安裝包http://www.mongodb.org/downloads我的系統是redhat5.8所有選擇相應的版本包就ok現在最新版是3.0.3

2. 解壓mongodb-linux-x86_64-rhel55-3.0.3.tgz

[[email protected] ~]# tar zxvf mongodb-linux-x86_64-rhel55-3.0.3.tgz -C /opt/mongodb-linux-x86_64-rhel55-3.0.3/READMEmongodb-linux-x86_64-rhel55-3.0.3/THIRD-PARTY-NOTICESmongodb-linux-x86_64-rhel55-3.0.3/GNU-AGPL-3.0mongodb-linux-x86_64-rhel55-3.0.3/bin/mongodumpmongodb-linux-x86_64-rhel55-3.0.3/bin/mongorestoremongodb-linux-x86_64-rhel55-3.0.3/bin/mongoexportmongodb-linux-x86_64-rhel55-3.0.3/bin/mongoimportmongodb-linux-x86_64-rhel55-3.0.3/bin/mongostatmongodb-linux-x86_64-rhel55-3.0.3/bin/mongotopmongodb-linux-x86_64-rhel55-3.0.3/bin/bsondumpmongodb-linux-x86_64-rhel55-3.0.3/bin/mongofilesmongodb-linux-x86_64-rhel55-3.0.3/bin/mongooplogmongodb-linux-x86_64-rhel55-3.0.3/bin/mongoperfmongodb-linux-x86_64-rhel55-3.0.3/bin/mongodmongodb-linux-x86_64-rhel55-3.0.3/bin/mongosmongodb-linux-x86_64-rhel55-3.0.3/bin/mongo[[email protected] opt]# ln -sv mongodb-linux-x86_64-rhel55-3.0.3/ mongodbcreate symbolic link `mongodb‘ to `mongodb-linux-x86_64-rhel55-3.0.3/‘

3.建立mongodb使用者

[[email protected] /]# useradd mongodb

4.建立相應檔案目錄並修改許可權

[[email protected] /]# mkdir /data/db -p[[email protected] /]# chown mongodb:mongodb /data/ -R[[email protected] opt]# chown -R mongodb:mongodb /opt/*

5.添加PATH環境變數在shell下正常訪問mongodb的應用工具

[[email protected] bin]# vim /etc/profile.d/mongodb.shexport    PATH=$PATH:/opt/mongodb/bin[[email protected] bin]# source /etc/profile.d/mongodb.sh [[email protected] bin]# echo $PATH /usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/opt/mongodb/bin

6.建立mongodb的PID存放目錄

[[email protected] run]# mkdir /var/run/mongodb[[email protected] run]# chown mongodb:mongodb /var/run/mongodb/ -R[[email protected] opt]# mongod --dbpath /data/db/ --logpath /var/log/mongodb.log --logappend --port 27017 --pidfilepath /var/run/mongodb/mongodb.pid --maxConns 250 --rest --httpinterface --forkabout to fork child process, waiting until server is ready for connections.forked process: 4060child process started successfully, parent exiting--maxConns 250 ：表示最大串連數是250個--rest --httpinterface : web介面，指定這項28017連接埠才能啟用--fork ：後台運行

7.安裝過程中遇見的問題

裝好之後串連出現以下警告

(1).[[email protected] ~]# mongoMongoDB shell version: 3.0.3connecting to: testServer has startup warnings: 2015-06-15T20:27:49.892+0800 I CONTROL  [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended.2015-06-15T20:27:49.892+0800 I CONTROL  [initandlisten]

出現這個問題就查看關於mongodb的檔案許可權，主要是/opt /data/db/ /var/run/mongodb/ /var/log/mongodb.log的許可權因為啟動初始化時以root使用者的許可權在運行，所以這些目錄下的許可權可能會變成root root

(2).[[email protected] db]$  mongod --dbpath /data/db/ --logpath /var/log/mongodb.log --logappend --port 27017 --pidfilepath /var/run/mongodb/mongodb.pid --maxConns 250 --rest --httpinterface --fork2015-06-15T17:41:25.721+0800 I CONTROL  [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is ‘always‘.2015-06-15T17:41:25.721+0800 I CONTROL  [initandlisten] **        We suggest setting it to ‘never‘2015-06-15T17:41:25.721+0800 I CONTROL  [initandlisten] 2015-06-15T17:41:25.721+0800 I CONTROL  [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is ‘always‘.2015-06-15T17:41:25.721+0800 I CONTROL  [initandlisten] **        We suggest setting it to ‘never‘

修改兩個參數即可

echo "never" > /sys/kernel/mm/transparent_hugepage/enabled echo "never" > /sys/kernel/mm/transparent_hugepage/defrag

 8.安裝成功並登入

 [[email protected] ~]# ss -tanlp | grep mongod0      0                              *:27017                         *:*      users:(("mongod",4095,6))0      0                              *:28017                         *:*      users:(("mongod",4095,8)) [[email protected] ~]# mongoMongoDB shell version: 3.0.3connecting to: test> help    db.help()                    help on db methods    db.mycoll.help()             help on collection methods    sh.help()                    sharding helpers    rs.help()                    replica set helpers    help admin                   administrative help    help connect                 connecting to a db help    help keys                    key shortcuts    help misc                    misc things to know    help mr                      mapreduce    show dbs                     show database names    show collections             show collections in current database    show users                   show users in current database    show profile                 show most recent system.profile entries with time >= 1ms    show logs                    show the accessible logger names    show log [name]              prints out the last segment of log in memory, ‘global‘ is default    use <db_name>                set current database    db.foo.find()                list objects in collection foo    db.foo.find( { a : 1 } )     list objects in foo where a == 1    it                           result of the last line evaluated; use to further iterate    DBQuery.shellBatchSize = x   set default number of items to display on shell    exit                         quit the mongo shell

9.關閉伺服器

(1).[[email protected] ~]# mongod --shutdown killing process with pid: 3936(2).[[email protected] ~]# killall mongod

10.給mongodb編寫設定檔/etc/mongodb.conf

[[email protected] ~]# grep -v ^# /etc/mongodb.conf logpath=/var/log/mongodb.loglogappend=truefork = truedbpath=/data/dbpidfilepath = /var/run/mongodb/mongodb.pidrest = truehttpinterface = true

啟動

[[email protected] ~]# mongod -f /etc/mongodb.conf about to fork child process, waiting until server is ready for connections.forked process: 4169child process started successfully, parent exiting[[email protected] ~]# ss -tanlp | grep mongod0      0                              *:27017                         *:*      users:(("mongod",4169,6))0      0                              *:28017                         *:*      users:(("mongod",4169,8))

11.用service mongodb * 來啟動mongodb
啟動指令碼：/etc/rc.d/init.d/mongod
